RAZOR-STROPPER.

Specification of Letters Patent.

l atented May 3, 1910.

Application filed'll'une 21, 1909. Serial No. 508,270.

which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to devices for holding razor blades while honing, stropping or otherwise sharpening the same and has reference more particularly to a holder adapted for use with cutting blades of the Gillette type, and with cutting blades wherein one edge thereof is provided. wlth a portion of increased thickness or wherein one be inexpensive and that will hold the blade at the correct angle to meet the strop or hone irrespective of the type of the blade.

With these and other objects in view the invention consists of the novel construction hereinafter set forth in the specification and illustrated in the drawings, it being understood that various changes in form, proportion and construction may be made without departing from the spirit and scope of the invention.

in the accompanying drawing forming a part of my application: Figure l is a top view of the holder, with the two clamping members separated, in position to receive the blade, a blade of the Gillette type being shown in position in the holder; Fig. 2 shows the clamping members looked, a similar blade being in position ready for use; Fig. 3 shows the clan'iping members locked witn a single edge blade in position in the opposite end of the holder ready for use; Fig. 4 is a similar view showing a single edge blade without the reinforced portion or reinforcing member, in position for use; Fig. 5 is a similar View showing a tub-edge blade of another style in position ready for use; Fig. (5 is a View of the edge guard; and Fig. 7 is a View similar to that shown in Fig. 2 with the edge guard in position on the stroppcr. Fig. 8 is an edge View the holder being partly broken away.

The particular embodiment of my invention selected for illustration herein comprises, Fig. 1, a holder having two clamping members a and b, pivotallyconnected at one end at 0, one of the said members, herein a, being provided at its free end with the posts d and c, the other member Z) beingprovided with cooperating openings f and g to receive said posts. The clamping member a is provided, intermediate its ends, with a locking device 71., pivoted thereto atz', and

adapted to engage the member '6, thereby securely to position and lock the two members. Near their opposite ends, Fig. 1, the members a and Z) are cut away at one of their adjoining edges forming a longitudinal recess 7' forming shoulders is and Z at its ends. By means of this recessed portion blades similar to the type shown in Fig. 3 may be securely locked in the holder for stropping or honing. This type of blade is usually provided with a reinforcing memher at folded over one edge of the blade or a similarly shaped reinforced portion.

By positioning the blade, Fig. 3, so that the edge a of the reinforcing member or reinforcing portion of the blade abuts against the edge 0 of the recess 7' the ends 32 and q of the reinforced portion or reinforcing member m will be positioned between the shoulders 7c and Z and the blade efi'ectually secured against movement in the holder, after the clamping members are locked. By securing the blades in the manner described the cutting edge thereof is presented to the strop in proper position to be honed or stropped.

When it is desired to use the holder the locking device It is turned to one side and the member I), having avslight spring tension at its outer end, springs from enga ement with the pins (Z and c and may, if esired, then be moved laterally from the other memher a. The blade if of the type shown in Figs. 1 and 2, is 'then placed in position, one or more of the holes in the blade receiving the posts all and e. The member Z) is returned to its former position in line with member a, the apertures and 9 receiving the posts d and e, and the locking device h is returned to locking'position. When it is desired to use a'blade similar to that shown in Fig. 3 the clampin members a and b are separated as above escribed, the blade is of either the single or double edge type,

Figs. 4 and 5, not provided with the apertures for receiving the posts (Z and e or the reinforced portion or member in may be clamped between the pivoted ends of the holder and honed or stropped in a similar manner.

In the specific illustration of my improved device, Fig. l, the blade is held along a line falling between the opposite edges thereof whereby the two edges of a two-edge type of blade may be sharpened without necessity of unlocking the blade and reversing its position, as is necessary in the case of holders wherein only one edge of the blade is exposed at a time. If desired for any reason, a protector or the like, such as the edge guard 1*, may be slipped over one edge while stropping the other. The guard is preferably formed from a piece of thin metal so folded that along one edge 8, it fits closely to the sides of the blade. Near the opposite edge the two sides are upset to form a groove t suiliciently wide to admit the end of the holder, and again at its e2:-

treme opposite edge u the two sides are brought close together. This protector is made of spring metal and when slipped over the end of the blade at one edge thereof tits sufficiently tight to remain in position, and

by reason of the fact that it embraces the clamping members of the holder and at the same time engages opposite faces of the blade, it contributes to the rigidity and firmness with which the blade is held in and between the clamping members.

The advai'itagc of being able to sharpen both edges of the blade without unlocking and reversing its position is apparent.

[t is practicable, according to my lIlVQlk tion, to construct a holder without any hinge or locking device that could by any means scratch or injure the surface of the hone or strep; and this is of very material advanposition between them a blade of increased tagc although, of course, not. indispensable.

Claims 1. A device of the classdescribed, comprising clamping members adapted at each of their ends to clamp and position a blade flatwise between them and hinged together at their ends to swing apart in planes subblade, and locking means intermediate said hinged and clamping ends of said device forclamping members to lock the same to hold the blade in dilferent positions.

at. A razor blade stropper comprising, in combination, blade clamping members hinged together at one of their ends and adapted at their opposite ends to clamp between them a blade to be sharpened, a locking member cooperating with said clamping members intermediate their lengths to lock the same in blade clamping position, .and means including said locking member as an element for holding and positioning a blade to be sharpened at or near the hinged ends of said clamping members.

5. A razor blade stropper comprising, in combination, separable blade clampin members, means at one of the ends of sai members to hold a blade to be sharpened, locking means to lock said clamping members in blade clamping position, and means including said locking members as an element for locking and positioning an additional blade to be sharpened at or in the vicinity of the opposite ends of said clamping members.
